We often expose the proxy APIs that connect applications to their backend APIs. With a proxy API, the application continues to run without issue and continue to call and connect to the backend API while a developer is editing it. Exposing a proxy API also protects the backend API from the world, shielding the real IP address.
The advantage of using a proxy is having a layer of separation to ensure that any attacks against our API are stopped well before anyone interacts with our main servers.
